Description

  The present invention relates to a portable terminal device with a television function and a program for receiving and outputting television broadcast radio waves using a battery as a drive source.

In recent years, portable terminal devices having a television function capable of receiving a television broadcast and viewing a program of a desired channel have begun to spread. In this mobile terminal device with a TV function, a secondary battery is used as a drive source to receive and output TV broadcast radio waves. For TV video and audio output, such as lighting of a backlight that illuminates a liquid crystal screen, In order to consume high power, the battery runs out during viewing.
Therefore, conventionally, for example, a decrease in the remaining battery level is detected while watching TV, and power saving control is executed as the remaining battery level decreases. At that time, video / audio output is stepwise according to the remaining level. A technique is known in which recording of a television broadcast is started when the final level is reached (see Patent Document 1).
JP 2003-274313 A

  However, in the above-mentioned patent document, when the broadcast time of a program is long, even if the recording is started after detecting a decrease in the remaining battery level, not all the program contents can be recorded, and as a result Some of them may be overlooked. The same problem occurs even when the program viewing is started with the battery fully charged. Also, in the above-mentioned patent document, in consideration of the broadcast time until the end of the program, when the broadcast time until the end of the program exceeds a predetermined time (for example, 1 hour), the viewable time is achieved by performing power saving control. However, if the backlight that illuminates the LCD screen is driven at low power, the screen content becomes difficult to see, and depending on the length of the broadcast time, even if power saving control is performed, Similarly, not all the program contents can be recorded, and as a result, some of them may be overlooked.

Since the determination is made, when viewing the designated program, it can be known whether the battery runs out during the broadcast.

  According to the eighth aspect of the invention, the broadcast time of each TV broadcast program is acquired with reference to the electronic program guide, and received for each program until the end of the program based on the broadcast time and the current battery level. Since it is determined whether or not it is possible, and the determination result is identified and displayed on the electronic program guide, what programs can be received to the end by looking at the electronic program guide and what programs cannot be received The received program can be changed as necessary. For example, the broadcast time of sports news programs, etc., often varies greatly depending on the broadcast time zone or broadcast station. In such a case, the program is changed to a program that can receive all of the broadcast contents with the current battery level. If this is done, it will be possible to prevent viewing and recording from being interrupted during the broadcast, but of course, if the received program is not changed, the secondary battery can be charged or the battery replaced. It is also possible to cope with such a situation, and it is possible to effectively eliminate the inconvenience with respect to running out of the battery by appropriate correspondence.

  According to the invention described in claim 9, in addition to having the same effect as the invention described in claim 8 described above, the amount of power consumed per unit time when receiving a television broadcast is referred to for each program. Since the power consumption corresponding to the broadcast time is obtained, it is determined whether or not reception is possible until the end of the program with the remaining battery level based on the power consumption for each program and the current battery level. A reliable determination is possible based on the power consumption per hour.

  According to the invention described in claim 10, in addition to having the same effect as that of the invention described in claim 8, the predicted power consumption consumed from the present time to the start of broadcasting is obtained for each program, and the start of the program is started. Since the predicted power consumption consumed from the time to the end of the program is obtained, it is determined whether or not the program can be received until the end of the program with the remaining battery level based on the predicted power consumption and the current battery level. The predicted power consumption consumed from the present time to the start of broadcasting can also be taken into consideration, and more accurate discrimination is possible.

  According to the invention described in claim 11, in addition to having the same effect as that of the invention described in claim 8, it is determined whether or not the program can be received until the end of the program for each program listed on the electronic program guide. Since the receivable program and the unreceivable program are identified and displayed on the electronic program guide based on the determination result, the receivable program and the unreceivable program can be clearly identified. it can.

When the apparatus main body is placed (connected) on (charging base) 21, the secondary battery 18 is charged by receiving power supply from the AC power supply.

  In this case, external power supplied from the cradle stand 21 in place of the secondary battery 18 serves as a drive source for the entire mobile phone device, and a TV function or the like is driven by power supplied from an external power supply (AC power supply). In other words, the TV function for receiving and outputting TV broadcast radio waves operates using the secondary battery 18 as a drive source. However, when connected to the cradle stand 21, the TV function operates using externally supplied power as the drive source. To do. When the apparatus main body is connected to the cradle stand 21, the charge / discharge control unit 19 receives power supplied from the AC power source to charge the secondary battery 18 and manages the charge amount based on the charge current. I do. Power is supplied to the entire mobile phone device via the charge / discharge control unit 19, and the charge / discharge control unit 19 manages the discharge amount of the secondary battery 18 based on the discharge current. Based on this charge / discharge amount, the charge / discharge control unit 19 detects the current remaining battery level of the secondary battery 18.

  FIG. 3 shows an example of the contents of the electronic program guide (EPG) 20. The electronic program guide 20 includes “start time”, “title”, and “comment” of each program for each channel (broadcast station). Etc. are posted. When the TV 1 receives and outputs a TV broadcast radio wave using the secondary battery 18 as a drive source, the CPU 1 searches the electronic program guide 20 to acquire the broadcast time of each TV broadcast program, and the broadcast time for each program. Whether or not the program can be received to the end based on the remaining battery level of the secondary battery 18 is determined. Based on the determination result, the receivable program and the unreceivable program are displayed on the electronic program guide 20. The identification is displayed. In this case, the electronic program guide 20 is displayed on the main display section 9, and a program that can be received and a program that cannot be received are identified and displayed on the electronic program guide 20.

  When a desired program is selected on the electronic program guide 20 by a user operation, the CPU 1 determines whether the designated program can be received to the end by the remaining battery level of the secondary battery 18, and the determination result Is notified before the broadcast of the designated program is started. In this case, the CPU 1 determines whether the designated program can be received and recorded to the end, or whether the designated program can be received and output to the end (video output and audio output). Discriminate based on broadcast time. As a result, it is impossible to output video and audio until the end of the program, but if the specified recording can be recorded to the end, a message indicating that recording is possible is displayed and output, and the specified program is output to the end. When video output and audio output are possible, a message indicating that output is possible is displayed and output. When recording is impossible as well as output, a message indicating that output and recording are not possible is displayed and output.

  Next, the operation concept of the mobile phone device according to the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment.

FIG. 4 and FIG. 5 are flowcharts showing a TV process that is started when a start of the TV function is instructed by a user operation.
First, when a desired channel is selected and designated by operating a channel selection key (step A1 in FIG. 4), the CPU 1 displays a TV screen on the main display unit 9, and then designates a designated channel from the television receiving unit 11. The contents of the broadcast program are received and output of the program contents (video display / audio output) is started (step A2). In this way, in the state of viewing the program that is currently being broadcast, the presence / absence of an operation for instructing channel change is checked (step A3), or the presence / absence of an operation for instructing reading of the electronic program guide 20 acquired in advance is checked (Step A4), the presence / absence of an operation for instructing the television end is checked (Step A5). Here, when a channel change instruction is received (YES in step A3), the process returns to the above-described step A1 and is switched to the reception output of the program currently being broadcast on the changed channel.

  If reading of the electronic program guide 20 is instructed (YES in step A4), the remaining battery level of the secondary battery 18 is acquired from the charge / discharge control unit 19 (step A6), and based on the current date and time. The electronic program guide 20 is searched, and program information for one hour is read for each channel on the basis of the current time (step A7). For example, if the current time is 7am, program information for all channels at 7am is read, and if it is 11:00 pm, program information for all channels at 11pm is read. Then, after designating one program as a processing target in order from the smallest channel number and the earliest broadcast start time in the program information (step A8), the reception output (from the present time to the end time of the designated program) The process proceeds to a predicted amount calculation process for obtaining a predicted battery consumption amount consumed for video output and audio output (step A9).

FIG. 6 is a flowchart detailing the predicted amount calculation process (step A9 in FIG. 3).
First, the CPU 1 acquires the start time and end time of the designated program specified as the processing target (step B1), and acquires the preset battery consumption per unit time during standby (step B2). The battery consumption at the time of standby is an average consumption of power of the secondary battery 18 consumed per hour in a state where the standby screen is displayed and output, and is fixedly set in advance. Value. Next, the CPU 1 calculates a predicted battery consumption amount P1 from the present time until the designated program is started (step B3). In this case, the battery consumed from the current time to the start of the program is calculated by calculating the waiting time from the current time until the designated program starts, and multiplying this waiting time by the battery consumption per unit time at the time of standby described above. A predicted consumption amount P1 is calculated.

  Further, the CPU 1 acquires a preset battery consumption per unit time at the time of television output (step B4). The battery consumption during TV output is an average power consumption of the secondary battery 18 consumed per hour during TV video and audio output, and is a value that is fixedly set in advance. is there. Next, the CPU 1 calculates a predicted battery consumption amount P2 from the start of the designated program to the end thereof (step B5). In this case, the battery consumption prediction from the start to the end of the program is calculated by calculating the broadcast time from the start to the end of the program and multiplying the broadcast time by the battery consumption per unit time at the time of television output described above. The amount P2 is calculated.

  By adding the estimated battery consumption amount P1 from the present time to the start of the program and the predicted battery consumption amount P2 from the start to the end of the program, the video output and audio output are consumed from the present time to the end of the program. The estimated battery consumption amount P1 + P2 is obtained (step A10 in FIG. 4), and the estimated battery consumption amount P1 + P2 is compared with the remaining battery level of the secondary battery 18 detected at the present time (step A11). On condition that the predicted amount is P1 + P2, an “OK flag” indicating that this designated program can be output (viewed) to the end is set corresponding to the program (step A12).

  Then, it is checked whether all the programs included in the current reading range have been designated as processing targets (step A13). That is, if the current reading range is 7:00 am, it is checked whether all the programs for all the channels in the 7 am range have been designated as processing targets, and the above-described step A8 is carried out until all the corresponding programs are designated. The above operation is repeated while returning and designating the next program. As a result, the “OK flag” is set in association with the designated program on the condition that the remaining battery amount> the predicted battery consumption amount P1 + P2 (steps A8 to A13).

  As a result, when all the programs within the current reading range have been specified (YES in step A13), a window screen for an electronic program guide is displayed on the TV video screen of the main display unit 9, and “ The program for which the “OK flag” is set is identified and displayed on the electronic program guide 20 (step A14). FIG. 8 is a diagram showing a state in which a program that can be output (viewed) until the end of the broadcast corresponding to each program is identified and displayed on the electronic program guide 20. Broadcast programs such as “7:00: Today's event”, “7:00: Weather forecast”, “7:00: World news”, etc. are output (viewed) until the end of the broadcast. However, “7:15: Drama ...”, “7:20: Morning wide show”, etc. cannot be output (viewed) until the end of the broadcast. It is clearly indicated that it is a program. Note that the method of identification display is not limited to the presence / absence of shaded display, and may be, for example, presence / absence of blinking display, color-coded display, enlarged display, and additional display of a message.

  As described above, in the state where the availability of viewing is identified and displayed on the electronic program guide 20 corresponding to each program in the current reading range, an instruction operation for instructing to be updated in the next time zone is performed. (YES in step A15), that is, for example, when the current read range is in the 7 am range, and when the update is instructed, the next time zone is the 8 am range time range. After reading each program information within this range from the electronic program guide 20 (step A16), the process returns to the above-described step A8, and the above-described operation is repeated thereafter. As a result, corresponding to each program of the next 8 o'clock in the morning, the availability of viewing is identified and displayed on the electronic program guide 20. Here, when an operation for selecting and specifying an arbitrary program on the electronic program guide 20 (for example, a touch operation) is performed (YES in step A17), the process proceeds to step A21 in FIG. Is performed (YES in step A18), the screen of the electronic program guide 20 is switched to the video screen of the currently received broadcast program.

  If a desired program is selected and designated on the electronic program guide 20, it is checked whether or not the “OK flag” is set for this designated program (step A21 in FIG. 5). "Is set when the current remaining battery level is larger than the estimated battery consumption P1 + P2 consumed by the video / audio output from the current time until the end of the designated program as described above. If the “OK flag” is set, the remaining battery level> the estimated battery consumption amount P1 + P2, and the output is possible until the end of the designated program. Therefore, a message screen (window screen) indicating that video / audio can be output. Is displayed and output on the television image screen (step A22).

  If the “OK flag” is not set for the designated program (NO in step), the battery consumption per unit time consumed during recording of the television broadcast is acquired (step A30). The battery consumption at the time of recording is an average power consumption of the secondary battery 18 consumed per hour at the time of recording a television broadcast, and is a value set in advance in a fixed manner. Next, based on the battery consumption per unit time and the broadcast time from the start to the end of the designated program, a battery consumption prediction amount P3 from the start to the end of the recording is calculated (step A31). Then, by adding the predicted battery consumption amount P1 and the predicted battery consumption amount P3, the predicted battery consumption amount P1 + P3 consumed by the recording from the present time to the end of the designated program is calculated (step A32). The predicted consumption amount P1 + P3 is compared with the remaining battery level of the secondary battery 18 detected at the present time (step A33).

  If the remaining battery level is greater than the estimated battery consumption amount P1 + P3 (YES in step A33), a message screen (window screen) indicating that recording is possible, but output is impossible until the end of the program, is a television image. A message is displayed on the screen (step A34). If the remaining battery level is equal to or less than the estimated battery consumption P1 + P3 (NO in step A33), a message screen message screen indicating that the output and recording are impossible until the end of the program ( (Window screen) is displayed and output on the television image screen (step A35). FIG. 9A shows a message screen when recording is possible, and FIG. 9B shows a message screen when output and recording are not possible. A message prompting charging of the secondary battery 18 is also displayed on the message screen.

  Here, it is checked whether or not the user has instructed to reserve viewing of the designated program in the state in which the above-described output enabled message screen is displayed (step A23). This reservation for viewing reserves that notification to prompt viewing of this program should be made prior to the start of reception and output of the specified program. When this reservation for viewing is instructed, the reservation for viewing is reserved for the specified program. While setting (step A24), a viewing reservation flag is set (step A25). Further, in the state in which the above-described output enabled or recordable message screen is displayed and output, it is checked whether the user has instructed recording reservation for the designated program (step A26). A recording reservation is set for the designated program (step A27), and a recording reservation flag is set (step A28). When such a viewing reservation or recording reservation is made or when a return operation is performed (step A29), the process returns to step A15 in FIG.

FIG. 7 is a flowchart showing an operation that is automatically started by a timer interruption when the reservation date / time arrives when the TV recording reservation / viewing reservation is set.
First, when the TV function is started by the timer when the recording reservation date / time or the viewing reservation date / time is reached, the CPU 1 selects the reserved channel (step C1), and then the above-mentioned “recording reservation flag” is set. (Step C2), and if the recording reservation flag is set, recording of the reserved program is started (step C3), and then the recording reservation flag is reset (step C4). If the viewing reservation flag is set (NO in step C2), the user is notified of the start of the reserved program by displaying a message, generating an alarm sound, or the like (step C5). In this case, vibration notification may be performed instead of the alarm sound. Thereafter, the viewing reservation flag is reset (step C6).

  As described above, in the first embodiment, the CPU 1 obtains the remaining battery level of the secondary battery 18 from the charge / discharge control unit 19, and the arbitrarily designated broadcast program is reached to the end according to the current remaining battery level. It is determined whether or not the program can be received, and the determination result is notified and output from the main display unit 9 before the broadcast of the specified program is started. The designated program can be changed as necessary. For example, the broadcast time of sports news programs, etc., often varies greatly depending on the broadcast time zone or broadcast station. In such a case, a program that can receive all of the broadcast contents with the current battery level is specified. If this is done, it is possible to prevent viewing and recording from being disabled during the broadcast, but of course, if the designated program is not changed, the secondary battery can be charged or the battery replaced. It is also possible to cope with such a situation, and it is possible to effectively eliminate the inconvenience with respect to running out of the battery by appropriate correspondence.

  In this case, when the program to be reserved for recording is designated in advance, the CPU 1 determines whether or not the designated program can be recorded to the end, and if it is possible to record to the end of the program, Since a program recording reservation is made, a recording reservation can be made for a program that can be recorded with the current remaining battery level, and a recording reservation for a program that cannot be recorded can be invalidated. Here, whether or not the reserved program can be recorded to the end based on the predicted power consumption consumed from the present time to the start of broadcasting of the reserved program and the predicted power consumption consumed from the start to the end of the reserved program Therefore, it is possible to consider the predicted power consumption consumed from the present time to the start of broadcasting of the reserved program, and more accurate determination is possible. In addition, prior to the start of receiving and outputting the designated program, when making a reservation for viewing the program, it is determined whether or not the designated program can be received and output to the end. Viewing reservations can be made for programs that can be received and output.

The CPU 1 acquires the broadcast time of each broadcast program with reference to the electronic program guide 20, and determines whether or not the program can be received to the end of the program based on the broadcast time and the current remaining battery level for each program. Since the discrimination result is identified and displayed on the electronic program guide 20, it is possible to know what programs can be received to the end and what programs cannot be received by viewing the electronic program guide. The received program can be changed as necessary. This makes it possible to prevent the inability to view and record during the broadcast, as well as to charge the secondary battery or replace the battery. Inconvenience can be effectively eliminated. Also in this case, the predicted power consumption consumed from the present time to the start of broadcasting can be taken into consideration, and more accurate discrimination is possible.
(Example 2)

The second embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment described above, when making a recording reservation or viewing reservation, it is determined whether or not the designated program can be received until the end. In this second embodiment, the designated program is determined. When receiving or recording the received program, it is determined whether or not the designated program can be received until the end.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 10 and FIG. 11 are flowcharts showing TV processing that is started when a television reception recording or reception output is instructed by a user operation / recording reservation timer activation in the second embodiment.
First, the CPU 1 acquires the remaining battery level of the secondary battery 18 from the charge / discharge control unit 19 (step D1 in FIG. 10), searches the electronic program guide 20 based on the current date and time, and uses the current time as a reference. The program information currently being broadcast or immediately before the broadcast is read for each channel (step D2). For example, if the current time is 7:59 am or 7:03 am, program information for all channels starting from 7:00 am is read. Then, from the program information, the one program is designated as a processing target in ascending order of channel number (step D3). Here, it is determined which of the television reception recording or reception output is instructed (step D4).

  Here, if reception recording is instructed, the battery consumption prediction amount P11 consumed by the reception recording from the present time to the end of the designated program is calculated (step D5). That is, the battery consumption per unit time at the time of television reception recording set in advance is acquired, the broadcast time until the program ends is calculated, and the battery consumption per unit time at the time of the television recording is calculated as the broadcast time. By multiplying the amount, a predicted battery consumption amount P11 consumed by the end of the program is calculated. In this case, if the current time is before the start of the program, the predicted battery consumption P11 from the start to the end of the program is calculated. If the current time is after the start of the program, the predicted battery consumption P11 from the current time to the end of the program is calculated. Then, the predicted battery consumption amount P11 and the remaining battery level of the secondary battery 18 are compared (step D6), and this designated program is recorded to the end on condition that the remaining battery level is greater than the predicted battery consumption amount P11. An “OK flag” indicating that it is possible is set corresponding to the program (step D9).

  Similarly, when the reception output is instructed, the battery consumption prediction amount P12 consumed by the reception output (video output and audio output) from the present time to the end of the designated program is calculated (step D7). That is, the battery consumption per unit time at the time of television reception output set in advance is acquired, and the broadcast time until the program ends is calculated, and the battery consumption per unit time at the time of television output is calculated as the broadcast time. By multiplying the amount, a predicted battery consumption amount P12 consumed by the end of the program is calculated. Even in this case, if the current time is before the start of the program, the predicted battery consumption P12 from the start to the end of the program is calculated. If the current time is after the start of the program, the predicted battery consumption P12 from the current time to the end of the program is calculated. calculate. Then, the battery consumption prediction amount P11 is compared with the battery remaining amount of the secondary battery 18 (step D8), and the designated program is output to the end on condition that the battery remaining amount> the battery consumption prediction amount P12. An “OK flag” indicating that it is possible is set corresponding to the program (step D9).

  Thereafter, the process returns to the above-described step D3 until all programs currently being broadcast or immediately before the broadcast are designated (YES in step D10). Here, when all the programs have been designated, the program for which the “OK flag” is set is identified and displayed on the electronic program guide 20 (step D11), as in the first embodiment described above. In this state, it is checked whether a desired program is selected and designated on the electronic program guide 20 (step D12) or an instruction to end the television is given (step D13). If it has been received, it is determined which of the TV reception recording or reception output is instructed (step D14).

  If reception recording is instructed (YES in step D14), it is checked whether the “OK flag” is set for the designated program (step D15). If the “OK flag” is set, That is, if the designated program can be recorded to the end, reception recording of the designated program is started (step D15), but when the “OK flag” is reset, a message screen indicating that recording is impossible is displayed and output. (Step D17). If reception output is instructed (NO in step D14), it is checked whether the “OK flag” is set for the designated program (step D18). If the “OK flag” is set, that is, If the designated program can be output to the end, reception output of the designated program is started (step D19), but when the “OK flag” is reset, a message screen indicating that output is impossible is displayed and output. (Step D20).

  As described above, in the second embodiment, the CPU 1 determines whether or not the designated program can be recorded to the end when the reception recording of the designated program is instructed by the user operation / recording reservation timer activation. When the specified program can be recorded to the end, recording of the program is started. When recording is impossible, a message to that effect is displayed. In addition, it is possible to quickly charge the secondary battery 18 and replace the battery by notifying that recording is not possible. In this case, when determining whether or not the designated program can be recorded to the end, the predicted power consumption consumed during the period based on the recording time (broadcast time) from the current time to the end of broadcasting of the designated program is obtained. Since it is determined whether or not the content of the designated program can be recorded from the predicted power consumption to the end, for example, even when recording is started in the middle of broadcasting, accurate determination is possible.

  When the CPU 1 is instructed to receive and output the designated program by a user operation, the CPU 1 determines whether or not the designated program can be output to the end, and when the designated program can be output to the end, Since the reception of the program is started and a message is displayed when the output is not possible, it is possible to prevent the inability to view the broadcast during broadcasting, and the secondary notification by the output disable notification. The battery 18 can be quickly charged and replaced. In this case, when it is determined whether or not the designated program can be output to the end, the predicted power consumption consumed during that time is calculated based on the broadcast time from the current time to the end of the broadcast of the designated program. Thus, it is determined whether or not the content of the designated program can be output to the end, and therefore, accurate determination is possible even if the output is started in the middle of broadcasting.

  At the time of reception recording or output of a television broadcast, the CPU 1 searches the electronic program guide 20 based on the current time, reads program information currently being broadcast or immediately before the broadcast for each channel, and completes the end of each program until the end. Since it is determined whether or not reception recording / reception output is possible, and the result is displayed on the electronic program guide 20 so as to be identifiable, it is similar to the same time zone such as a news program and a weather forecast. When a program to be broadcast is broadcasted, it is possible to select a program that can be received / recorded / received from the program currently being broadcast or immediately before the broadcast to the end.

  In the first and the above-described embodiments, the battery consumption required until the end of the program is calculated as described above in order to determine whether the broadcast program can be received / recorded / output until the end. However, the recordable time / viewable time with the current remaining battery level may be calculated. For example, the average value i of the discharge current for the last 10 seconds is acquired from the charge / discharge control unit 19, the current battery remaining amount (remaining amount in milliamps) c is acquired from the charge / discharge control unit 19, and the battery remaining amount c The average current value i is calculated to calculate the recordable time / viewable time (time in units of 10 seconds) t1 with the current remaining battery level. Then, by comparing this recordable time / viewable time t1 and the broadcast time t2 until the end of the program calculated as described above, it is determined whether or not recording / viewing is possible until the end of the broadcast program. May be. Here, if t2 ≦ t1, it can be determined that the broadcast program can be recorded / viewed to the end.

  In addition, when calculating the battery consumption from the current time until the start of the broadcast program, the battery consumption per unit time at the standby time set in advance is used as a reference. The amount is not limited to the standby time, but may be a value that takes into account the battery consumption during the average incoming / outgoing call.

  In addition, the secondary battery 18 is charged when connected to the cradle stand 21 (when the AC power supply is connected), but it may be replaced with a new battery or refilled with a battery pack. In addition, the present invention is not limited to a mobile phone device with a TV function, and can be applied to a mobile terminal device such as a PDA with a TV function, an electronic camera, an electronic wristwatch, and a music player. .
